Mixed-metal pillared layer clays (Fe,Al-PILCs and Cr,Al-PILCs)
of various compositions and the pillaring precursors have been
prepared and characterised with a combination of chemical and
instrumental methods. Chemical analysis data, IR, (57)Mossbauer
and Al-27 NMR spectroscopic measurements on the precipitated
pillaring precursors and comparison of redox behaviour
[temperature-programmed reduction (TPR) results and Fe-57
Mossbauer measurements on the heat-treated and the reduced
samples] of the ion-exchanged and Al-pillared and mixed-metal
pillared clays revealed that isomorphous substitution of Al for
Fe or Cr did not occur in either the tetrahedral or the
octahedral positions. Heat treatment, however, resulted in
mixed-metal pillared clays which were active in both acid-
catalysed and redox transformations.
